Although McDonald's ranks high on the list, the world's largest hamburger chain's no. 46 ranking is down from its previous rank at 22. Their 2015 spot is the lowest they have sat in the seven years they've appeared in the top 50.

Fortune says “consumer criticism over the company’s menu offerings, as well as a series of protests by labor rights activists over minimum wage” contributed to its lower ranking. However, the magazine says “with CEO Don Thompson’s recent ouster, McDonald’s is now tasked with a major turnaround.”

Apple took the top spot on the list for the eighth year in a row, becoming the first company to hit more than $700 billion in market value. Google, Berkshire Hathaway, Amazon.com and Starbucks also place in the top 5.
